In a crunch, I just upgraded my 3.x splunk to the latest, due to 2010 issues... didn't read the fine print and just found (after converting to a free license) that my scheduled searches are gone. That's a real bummer, since I used that for scripting other actions.
Usually, new versions ADD functionality, not take away.
Now, I have to figure out how to revert to 3 and solve the 2010 issues a different way.
